The British Antarctic Survey determined that the crack has expanded by 50 miles since 2011.
"It is particularly hard to predict when it will occur," Adrian Luckman of Project MIDAS told USA TODAY about the eventual calving, which would create a Delaware-sized iceberg. "I am quite surprised as to how long it is holding on!"
"The rift (or crack) has continued to open, and the berg continues to drift outward at a very consistent rate," Luckman added.
However, he noted that the crack has not grown longer in recent weeks.
As EcoWatch mentioned previously, the loss of this portion of the ice shelf will not raise sea levels as it is already floating on the water. However, as these ice shelves disintegrate, the land-locked glaciers they hold back may begin sliding into the sea. If all of the ice the Larsen C ice shelf holds back slides into the ocean, it will raise sea levels globally by four inches.
According to Project MIDAS, "there is not enough information to know whether the expected calving event on Larsen C is an effect of climate change or not, although there is good scientific evidence that climate change has caused thinning of the ice shelf."
Temperatures at the Antarctic Peninsula, where the Larsen ice shelf is found, have risen by 2.5 degrees Celsius in the past 50 years.
Antarctica's ice shelves are indeed melting rapidly as ocean waters warm. Climate Nexus reported in October that three glaciers in West Antarctica have undergone "intense unbalanced melting," risking their stability and further acceleration of sea level rise.
Research published in Nature Communications found that the Smith, Pope and Kohler glaciers in the Amundsen Sea embayment collectively lost about 1,000 feet of ice from 2002 to 2009.

Governors in Vermont and Maine signed bills on Monday that will ban plastic bags in their states next year, The Hill reported.
The Maine ban will go into effect next Earth Day, April 22, 2020. The Vermont ban, which extends beyond plastic bags and is the most comprehensive plastics ban so far, will go into effect in July 2020. The wait time is designed to give businesses time to adjust to the ban.

Lisa Marshall isn't your typical activist. For one thing, she's not into crowds. "I don't really like rallies," Marshall, a mom of three from upstate New York, said. "They're a little stressful — not my favorite thing."
Total Ban on Fracking Urged by Health Experts: 1,500 Studies Showed 'Damning' Evidence of Threats to Public Health, Climate
By Jake Johnson
A comprehensive analysis of nearly 1,500 scientific studies, government reports, and media stories on the consequences of fracking released Wednesday found that the evidence overwhelmingly shows the drilling method poses a profound threat to public health and the climate.

A new Environmental Working Group (EWG) study published in Environmental Research found that nitrate, one of the most common contaminants of drinking water, may cause up to 12,594 cases of cancer per year, but that's not its only danger: It can pose unique health risks to children.
Former coal lobbyist and Trump-appointed U.S. Environmental Protection Agency (EPA) Administrator Andrew Wheeler signed a rule Wednesday that officially replaces the Obama-era Clean Power Plan with a new regulation that Wheeler said could lead to the opening of more coal plants, the Associated Press reported.
